TOY DERRICK.

Specication'of Letters Patent.

Patented Dec. 7, 1909.

Application led March 25, 1909. Serial No. 485,725.

To all whom t may concern:

Be it known that I, MARCUS T. C. WING, a citizen of the United States, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Toy Derricks, of which the following is a specification, reference being had to the accompany- 4 ing drawings.

This invention -relates to improvements in toys and more particularly toys of the character set forth in my application for patent, Serial Number 435,315, filed May 27, 1908.

The object of the invention is to provide a toy of this character composed of a plurality of metal parts which may be readily taken apart and put together again and which may be put together in different ways to provide a toy derrick, tower, or various other mechanical, architectural and engineering structures.

With the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of a toy derrick embodying the present invention ;l Fig. 2 is a vertical sectional view through the same; Fig. 3 is a detail front elevation of the winding drum and portions of the parts associated therewith; Fig. 4 is a horizontal section through the drum and parts shown in Fig. 3; Fig. 5 is a detail perspective of one section of the drum; Fig. 6 is a detail perspective of the crank shaft of the winding drum; Fig. 7 is a perspective view of the rotatable drum carrying frame and its re tarding arm; Fig. 8 is a detail perspective of the retarding arm; Fig. 9 is a perspective view of the derrick cap; and Fig. 10 is a front view of the pulley block or hanger at the outer end of the boom.

In the drawings 1 denotes an upwardly tapering frame composed of metal strips or bars resembling a derrick, oil well tower, windmill tower, etc. It is composed of four angle metal corner bars 2 having their angles turned inwardly and their converging upper ends arranged in overlapping engagement with each other and united by means of a cap 3 and a transverse bolt 4. The cap 3 is of substantially inverted U-shape and has in its opposite depending flanges openings to register with openings in the flanges of the corner bars 2 for the reception of theA bolt or other fastening pin 4. Upon the top of the de-rrick cap 3 is an eye 5 for a purpose presently explained. The diverging lower ends of the corner bars 2 are secured by bolts 6 to four connecting base bars 7 also preferably of angular shape in cross section. Two of the base bars 7 have their channels disposed downwardly and inwardly while the other two have their channels disposed upwardly and inwardly, as clearly shown in Fig. 1 of the drawings. If desired, these base bars may be further united by crossed or diagonal strips 8 which reinforce and strengthen the tower and which have their ends connected by bolts 9 to the lower flanges of opposing bars 7 and which also have their intersecting central portions united by a bolt 10. If desired, the other portions of the derrick frame may be similarly united by diagonal bracing strips and openings 1l are formed at intervals in the corner bars 2 for the reception of bolts which fasten such bracing strips. Said openings 11 to gether with similar openings 12 formed in the base bars 7 permit these parts to be connected together in different ways to produce different kinds of toys.

13 denotes a boom hung upon a horizontal `pivot which is arranged in a support or frame 14 mounted in turn upon a substantially vertical pivot so that the boommay 1 swing both vertically and horizontally.

Said boom is composed of two bars 15 preferably of channel or U-shape in cross section, as shown more clearly in Fig. 3 and disposed with their channels outwardly. The lower or inner ends of the bars 15 have their flanges bent or folded over upon their body portions, as shown at 16, and said ends are apertured to receive a horizontal pivot 17, which latter is in the form of a shaft, one end of which is bent to form a crank handle 18 and the other end of which is screw threaded, as shown at 19. Said pivot or shaft 17 also extends through and is rota# table in bearing openings formed in vertical side bars 2O of the frame 14, which latter is of rectangular shape Vand constructed preferably from a single piece of channel bar, as clearly shown in Fig. 7 of the drawings. ln constructing said frame, such piece of channel bar has its flanges notched at the four points at which it is bent to provide the four corners of the frame 14. r

, rotation.

:ment .and frictionally retaining the frame in adjusted position, a retarding or bra-he arm 23 is provided. The latter is in the form of va metal plate having one end arranged beneath the bottom bar of the frame 14 and secured to the same by the lower pivot bolt 21, said arm being prevented from turning fupon the pivot bolt by forming or crimping it in a transverserib 2l which engages the bottom portion of the frame 14, as clearly .shown in Figs. 1 and 2. The free inner end ofthe arm 23 is adapted to swing under the brace strips 8 of the derrick frame, which latter frictionally hold it in adjusted position andthereby hold the frame 1st againstl The inner end of the retarding arm 23vcarries a bolt 25 which serves as a stop to engage one of the bars 7 to limit the swinging movement of the frame or support .llandhence thehorizontal swinging movement of the boom.

The outer ends of theboombars 15 are united by a xtransverse rpivot bolt 26 from which hangs a Aswinging pulley block or support 27 in the form of a metal plate bent upon itself or into U-form, as shown in Fig. 10,

.and having its closed end reduced, as shown at 28, for the attachment of-one end of a lcord 29. The latter passes around a pulley 30 in a block 31 whichhas a hook 32 from which any load mayzbe suspended. As illustrated, a pan 33 is supported from the hook for the reception of various objects or loose material suchas sand which children freyquently play with, but it will be understood ythat any objects or articles may be suspended from the hook 32 and lifted `by means of the cord 29. Said cord, after leaving the pulley 30 passes around a pulley 3l jonrnaled in the lower portion ofthe support 27 and from said pulley the cord passes downwardly between the bars 15 of the boom land to a winding drum or windlass arranged upon the shaft 17. Journaled upon the `pivot bolt 26 in the upper portion of the support 27 is a pulley 35 around which passes a cord 36 having one end attached to the eyeon the derrick cap and its other end,

after passing through the eye bolt 5, is

adaptedto be wound upon a cleat 37 fixed Yto one of the corner bars of the derrick. .will be seenthat by means of the cord 36, :the boom may beraised or lowered vertically and secured at any angle and that by means of the cord 29 the load upon the hoisting block 31 may be raised or lowered.

The winding drum is formed from two similar half-sections, each of which consists of a circular plate or disk 38 from which is stamped a tongue 39 so disposed that when the two disks or sections 38 are placed in opposition, as shown in Fig. 4f, the tongues 39 will be oppositely disposed to receive the shaft 17 between them. Said tongues 39 are channeled longitudinally so as to form opposing seats for the reception of the shaft 17 and their central portions are apertured to receive a fastening bolt l() which clamps the drinn or windlass to the shaft for rotation therewith. To prevent endwise movement of the shaft and to afford fastening for the cord, its portion within the drum is crimped or offset, as shown at 41, so as to extend around the bolt 40, as indicated in dotted lines in Fig. 3. By means of the crank -handle S the shaft and hence the drum may be rotated to wind up or pay out the cord 29, which latter has one end fixed to the drum.

Upon the threaded end 19 of the shaft 17 is preferably arranged a sprocket wheel Alf2 which may be used when it is desired to rotate the shaft 17 by a sprocket chain from a suitable motor or a power shaft. The

sprocket wheel t2 is formed from two metal disks secured upon the threaded. end of the shaft between nuts and interposed washers, as clearly shown in Fig. 1-, the edges or peripheries of said disks being bent outwardly, as shown at 44e, to produce a channeled rim and they are also crimped, as

. shown at 45, tovprovide sprocket projections,

as shown more clearly in Fig. 3, or a similar cast metal wheel may be used.

From the foregoing description, it will be seen that the toy is composed of a plurality of metalparts which may be readily taken apart and put together again and which can be put together in different ways to produce various architectural, mechanical and engineering structures according to the ingenuity of the child playing with the toy.

All parts of the toy are simple in construction so that they will be strong and durable and not easily broken, and they are of such shape that they may be readily nit together in different ways to produce difierent kinds of toys.
